An ordinary differential equation (ODE) form of the radial return algorithm, which is essentially a Prandtl-Reuss material model, is combined with a strain-rate hardening model to produce an ODE that describes deviatoric stress through a prescribed density rise. An analytical solution is found...

Focusing on the effects of policy on investment and innovation this paper examines whether the conceptual foundations of sector regulation are aligned with the current technological and economic conditions of advanced communications. One conclusion is that the prevailing theories and practices...

genotype-phenotype map in which concepts like plasticity, evolvability, epistasis and modularity not only can be precisely …. Molecular plasticity is viewed here primarily as the capacity of an RNA sequence to assume a variety of energetically favorable … shapes by equilibrating among them at constant temperature (microenvironmental plasticity). Through simulations based on …

We present a detailed statistical analysis of the size and temporal occurrence of burst sequences in the creep rupture of a proposed linear viscoelastic fiber bundle model. According to the model, the burst sequences of fiber breaks display a power law asymptotic behavior analogous to that of...

A simple evolutionary model is used to understand the critical rate of environmental change beyond which a population must decline and go extinct. The model is used to highlight the major determinants of extinction risk in a changing environment, and identify research needs for improved...
